Technical Field
[0001] This utility model relates to the field of sweater technology, and in particular to a high-density microporous waterproof and breathable knitted sweater. Background Technology
[0002] Knitted sweaters are an important part of modern clothing. Most knitted sweaters on the market are made of cotton yarn, chemical fiber yarn and other materials. They have a warm function and are a staple of people's clothing in autumn and winter. With the diversification of fabrics, the complexity of processes and the continuous progress of technology, knitted sweaters have been greatly improved in terms of style, comfort, warmth and breathability. Simply pursuing the warmth of the product can no longer meet people's needs. Only by developing knitted sweaters with multiple functions can we attract consumers' attention.
[0003] The existing patent publication number CN213045436U, entitled "A Knitted Sweater," proposes that the knitted sweater of this utility model has a wearable sleeve. The wearable sleeve is detachably connected to the main body of the knitted sweater by fastening or unfastening the male and female buttons on the wearable sleeve. This meets the actual needs of users. When people eat or do other activities, the sleeve covering the forearm is easy to get dirty. When washing, the entire knitted sweater needs to be washed, which is wasteful of resources. Washing the knitted sweater too frequently can cause it to deform. However, this utility model only requires removing the wearable sleeve and washing it separately, which reduces the number of times the main body of the knitted sweater needs to be washed and helps to extend the service life of the knitted sweater.
[0004] However, the windproof and waterproof knitted sweater disclosed in the appealed patent has poor breathability. In addition, the way the wearing sleeve is connected to the sleeve by a male and female button makes it easy for air to leak at the connection between the sleeve and the wearing sleeve, reducing the warmth of the knitted sweater. Therefore, it is necessary to propose a high-density microporous waterproof and breathable knitted sweater to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a high-density microporous waterproof and breathable knitted sweater to solve the problems mentioned above, such as the poor breathability of existing high-density microporous waterproof and breathable knitted sweaters, and the fact that the wearing sleeves are connected to the sleeves by male and female buttons, which makes it easy for air to leak at the connection between the sleeves and the wearing sleeves, thus reducing the warmth of the knitted sweater.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-density microporous waterproof and breathable knitted sweater, comprising a sweater body, a neckline at the upper end of the sweater body, sleeves on both sides of the sweater body, a wearing sleeve at the end of the sleeve away from the sweater body, a hem at the lower end of the sweater body, and the wearing sleeve being connected to the sleeve via a first connecting component.

A first hook surface is fixedly provided on the inner wall of the wearable sleeve end, and a first nap surface is fixedly provided on the inner wall of the sleeve end. The first nap surface is located above the second nap surface. The edge of the sleeve end is folded inward to form a first folded portion, and the edge of the wearable sleeve end is folded outward to form a second folded portion. The second folded portion and the first folded portion are interlocked with each other, and at this time, the first nap surface and the first hook surface are adhered to each other.
[0009] Preferably, the hem is connected to the sweater body via a second connecting component.
[0010] Preferably, the main body of the sweater includes, from the inside out, a skin-friendly layer, an antibacterial layer, and a breathable and waterproof layer. The skin-friendly layer is made of wool fabric, and the antibacterial layer is made of a blend of bamboo charcoal fiber, cotton fiber, and chitosan fiber. The skin-friendly layer and the antibacterial layer are sewn together with cotton thread.
[0011] Preferably, the breathable and waterproof layer is either a thermoplastic polyurethane elastomer film or a polytetrafluoroethylene film, which is fixed to the surface of the sweater body by hot stamping.
[0012] Preferably, the front end of the sweater body is provided with a storage bag, the upper and lower ends of the storage bag are sewn to the sweater body with cotton thread, both ends of the storage bag are connected to the sweater body by zippers, the inner wall of the storage bag is provided with an insulation layer, the insulation layer is made of fleece fabric, the structure of the storage bag and the sweater body are the same, and the storage bag and the insulation layer are sewn together with cotton thread.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. The second hook surface and the second nap surface facilitate the fixed connection between the wearing sleeve and the sleeve, and make the connection between the wearing sleeve and the sleeve more tight.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figures 1-4 The high-density microporous waterproof and breathable knitted sweater shown includes a sweater body 1, a neckline 2 at the upper end of the sweater body 1, sleeves 3 on both sides of the sweater body 1, a wearing sleeve 4 at the end of the sleeve 3 away from the sweater body 1, and an edge 5 at the lower end of the sweater body 1. The wearing sleeve 4 and the edge 5 are both elastic to prevent cold air from entering the garment from the cuffs or the bottom of the sweater, thereby improving the heat retention effect of the knitted sweater.
[0027] Considering that the sleeves 4 and hem 5 are most likely to come into contact with the outside when the sweater body 1 is worn, making them easily dirty and prone to pilling, the sleeves 4 are connected to the sleeves 3 via a first connecting component, and the hem 5 is connected to the sweater body 1 via a second connecting component. With the installation of the first and second connecting components, when the sleeves 4 and hem 5 get dirty, they can be easily removed for separate washing, thus reducing the number of times the sweater body 1 needs to be washed and extending the lifespan of the knitted sweater. Furthermore, when the sleeves 4 and hem 5 pill, they can be easily removed and replaced with replacement sleeves 4 and hem 5, thus avoiding the waste caused by discarding the entire knitted sweater.
[0028] Since the first connecting group and the second connecting component are similar in structure, this utility model takes the first connecting group as an example. Specifically, the first connecting component includes a second rough surface 10 fixedly disposed on the inner wall of the end of the sleeve 3, and a second hook surface 11 fixedly disposed on the outer ring of the end of the wearing sleeve 4 that extends into the sleeve 3. The second hook surface 11 and the second rough surface 10 are bonded to each other. The second hook surface 11 and the second rough surface 10 facilitate the fixed connection between the wearing sleeve 4 and the sleeve 3, and make the connection between the wearing sleeve 4 and the sleeve 3 relatively tight, preventing cold air from entering the garment from the cuff.
[0029] In addition, to enhance the stability and airtightness of the connection between the wearable sleeve 4 and the sleeve 3, a first support ring 6 is provided inside the structural layer at the end of the sleeve 3, and a second support ring 7 is provided inside the structural layer at the end of the wearable sleeve 4. Both the first support ring 6 and the second support ring 7 are made of elastic rubber. A first hook surface 9 is fixedly provided on the inner wall at the end of the wearable sleeve 4, and a first rough surface 8 is fixedly provided on the inner wall at the end of the sleeve 3. The first rough surface 8 is located above the second rough surface 10. The edge at the end of the sleeve 3 is folded inward to form a first folded part, and the edge at the end of the wearable sleeve 4 is folded outward to form a second folded part. The second folded part and the first folded part are interlocked with each other, and at this time the first rough surface 8 and the first hook surface 9 are bonded to each other.
[0030] After the second hook surface 11 and the second nap surface 10 are bonded together, the first support ring 6 and the second support ring 7 are flipped up simultaneously, so that the second folded part and the first folded part are interlocked, which can improve the airtightness of the connection between the wearing sleeve 4 and the sleeve 3. At this time, the first nap surface 8 and the first hook surface 9 are bonded together, which further improves the stability of the connection between the wearing sleeve 4 and the sleeve 3. This solves the problem that the wearing sleeve 4 on the sleeve 3 of the existing high-density microporous waterproof and breathable knitted sweater is connected to the sleeve 3 by male and female buttons, which makes the connection between the sleeve 3 and the wearing sleeve 4 easy to leak air and reduce the warmth of the knitted sweater.
[0031] Considering that existing high-density microporous waterproof and breathable knitted sweaters do not have waterproof and windproof functions when worn, wind, liquid rain and snow water can easily penetrate from the sweater into the human skin, resulting in poor cold protection and warmth retention, the main body 1 of the sweater in the utility model includes a skin-friendly layer 101, an antibacterial layer 102 and a breathable and waterproof layer 103 from the inside to the outside. The skin-friendly layer 101 and the antibacterial layer 102 are sewn together with cotton thread.
[0032] The skin-friendly layer 101 is made of wool fabric, which has the advantages of being strong and wear-resistant, lightweight, warm, elastic, wrinkle-resistant, highly absorbent, and comfortable to wear. In addition, wool fabric can absorb the moisture of the human body, making people feel dry and comfortable.
[0033] The antibacterial layer 102 is made of a blend of bamboo charcoal fiber, cotton fiber and chitin fiber, which gives this high-density microporous waterproof and breathable knitted sweater antibacterial properties, preventing the problem of mold and bacteria growth when damp.
[0034] In addition, by using a breathable and waterproof layer 103, which is either a thermoplastic polyurethane elastomer film or a polytetrafluoroethylene film, and fixing it to the surface of the sweater body 1 by hot stamping, this high-density microporous waterproof and breathable knitted sweater can have the breathable performance of windproof and waterproof clothing, and can adapt to the complex and changeable weather in winter, thus solving the problem of poor breathability of existing high-density microporous waterproof and breathable knitted sweaters.
[0035] Furthermore, a storage pocket 12 is provided at the front end of the sweater body 1. The upper and lower ends of the storage pocket 12 are sewn to the sweater body 1 with cotton thread. Both ends of the storage pocket 12 are connected to the sweater body 1 with zippers 13. The inner wall of the storage pocket 12 is provided with an insulation layer, which is made of fleece fabric. The structure of the storage pocket 12 and the sweater body 1 is consistent, and the storage pocket 12 and the insulation layer are sewn together with cotton thread. The storage pocket 12 makes it easy to place heat packs and other items inside, thereby improving the warmth of the high-density microporous waterproof and breathable knitted sweater. The zipper 13 and the insulation layer enable unidirectional heat transfer, thereby improving the heating effect.
